My mom buys food, it reminds me of data mining.

Remember to read a data mining book, the book begins with a small case. is a supermarket found daily diaper sales increase in the time of the same beer
Also sells particularly well. Later, the study found that the local lifestyle is that dad took the children mostly, so buy diapers at the same time buy beer, so this supermarket put
Beer and diapers and other young fathers need to take care of the children's products put together to facilitate the purchase of these milk dad. This is very convenient, you think Ah, the supermarket is very big.
It's a lot more trouble to find something to buy. Convenience for consumers. At the same time users will often go to this buy because it is very convenient province.

Dinner with my mom in the evening. I found a lot of vegetables in the vegetable leaves, asked, then alone to buy the lettuce? My mother said the supermarket do not, are the other people to buy vegetables to pick the dishes are removed, pick it up, supermarkets also do not care.
It's fresh and nutritious. Like we eat celery, usually eat celery stems, not celery leaves, in fact, celery leaves are very nutritious.

At that time I thought that the supermarket would not run,

First of all, if they find that consumers like to buy stems, you can get someone to pick up the vegetables, and then the leaves are sold separately, at a very cheap price to buy, even if no one to buy it's okay, anyway they used to throw,
Or they think they want to sell the lettuce at the same price as the stem, but the consumer will pick it up and not be supervised. will be removed, but after all, there are customers who do not pick, so they also earn money
But there is no denying that some consumers need to buy clean dishes, perhaps the supermarket has lost this part of the user

In another case, perhaps they were intentional. Deliberately making consumers profitable. Consumers can secretly take off their leaves. And then feel like you're taking advantage of it, and it's going to make an impression in your heart that this
The supermarket is good. I picked the leaves, and then came here to buy, thinking that they have benefited.


I think the real situation maybe the supermarket nobody notice this, I think a little more. But I think the behavior of these consumption and the things behind it is worth studying. Data mining is not just computer-to-cold data analysis. Also need to go into life, understand life
